The Azden SWS-30 is a professional windscreen accessory, commonly known as a "furry" or "dead cat" windshield, designed specifically for use with the Azden SMX-30 shotgun microphone and other microphones of similar size and shape. Its primary function is to protect the microphone's capsule from the disruptive and undesirable noise generated by wind blowing across it during outdoor recording. The furry exterior is highly effective at dissipating wind energy before it reaches the microphone's grille, dramatically reducing low-frequency rumble, buffeting sounds, and popping noises that can ruin an otherwise clean audio take. This makes the SWS-30 an essential tool for field production, documentary filmmaking, news gathering, and any on-location audio recording conducted in breezy or windy conditions.

Constructed from high-quality synthetic fur attached to a resilient foam base, the windshield is designed to slip securely over the microphone's body and shockmount. The foam layer provides initial wind resistance and physical protection, while the long, soft fibers of the exterior fur break up and slow down moving air masses. This two-stage design ensures superior wind noise suppression compared to basic foam windscreens alone. The SWS-30 is engineered for a precise fit on the SMX-30, ensuring it stays in place during movement and does not contact or rub against the microphone's grille, which could itself create noise. Its lightweight design does not impede the microphone's handling or mounting in a shockmount.

By mitigating one of the most challenging environmental factors in location audio, the Azden SWS-30 windshield enables audio engineers and videographers to capture clear, usable dialogue and ambient sound in a wide range of outdoor settings. It is a simple yet highly effective piece of acoustic treatment that significantly expands the usable environments for the shotgun microphone it is designed to protect.
